lle it known that ll, Anienrsr W. Bienen, a citizen 'ot the rUnitedStates, residing at llloomiield, in the county-ot avis, State ot lovva,have invented a nevv and useful lltotary Explosive-Engine; and l dohereby declare the following to he a lull, clear, and enact descriptionot the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

This invention relates to an improved rotary internal combustion engine,and an ohject ot' the invention is to provide an engine of this kindhaving simple, improved and practical features or" construction.

@ne ot the features ot construction is the n provision oiga casinghaving' intake ports, exhaust ports, and a hollovv cylinder valverotatahle in the casing and provided with a port to alternately registerwith the iirst ports, tor intaking and exhausting the interior ot thecylinder valve constituting the conihustion chamber, in which the pistonis reciprocated.

Another feature of the invention is to provide a multiple cylinderinternal combustion engine, in Which improved connections are providedhetvveen the crank shaft and the coinhined revoluble cylinder valve andcomhustion chamher casing so that when the ports ot said valvealternately register with the intake and exhaust ports of the casing,the piston will in turnA receive its charge, and exhaust the utilizedgases.

In practical iields'the details of construction may necessitate'alterations, .falling1 Within the scope ofwhat is claimed.

The invention comprises further features and combination of parte, ashereinafter set forth, shown inthe drawingsand claimed.

Mounted in hearings ot the crank casingsl and 2 is acrank shaft o, to which; the sprocket 'i' is hired hy means ot the keyor feather 8 that is, hetvveen the-two crank casings, and upon one endof the crank shaft 6 the drive pulley 9 is mounted. The shaft 6 isprovided with the cranks l0 and l1, to which the pitinan rods 12 and 13are connected by means oi the cap plates lt and bolts 15.l The upper endof each pitman terminates in the usual hearing sleeve positionl of thecylinder the en* et the 16.' The bearing sleeves .16 arev pivotallymounted upon the pins 17 on the interior of the pistons 18 and 19. Thecylinder casings are provided'vvith the usual cylinder heads 20, whichare secured to the upper ends of they cylinder casings by means of thebolts 2l. The cylinder heads 20 and the cylinder casings are providedwith the usual Water the usual sockets 23 for the spark plugs 24.- and25. its shown in Fi s. 2 to 5 inclusive it will he seen that thecylinder casing's are provided vvith intake and exhaust ports 26 and 27,and revolubly mounted in said cylinder casings are cylinder valves 28and 29,- which are suhof the same length as the cylder casings, and arehtted telescopically in said casing, but for revoluhle movementscomparatively loose therein, and these cylinder valves are providedvvith diametrically oppositely disposed ports 31 and 32, rotates throughjackets 22, and

' upon the shaft their connections with the crank shaft, said ports 31and 32 alternately register with the intake and exhaustl ports 26v and2'?. 1n other words, when the port 31 registers with the exhaust port27,'the utilized gases are exhausted; therefore the port 31 at this in#stance will constitute an exhaust port. FThen the ,port 31 will registerwith the intake port 26, thereby perm1tting an intake charge, and inthis case the port 31 will actas an intake port. rlhe same is true inregard to the port 32 as it registers with lirst the exhaust port 27 andthenv the intake port 26. rlhe usual intake and exhaust manifold 33 and34 are connected to the intake and exhaust ports 26 and 27, as seen inFig., 1. Mounted in bearings ot the upper art of the crank casings is ashaft 35, to w ich, a sprocket wheel 36 is fixed by means of the pin 37.The collars 38 which are secured 35 by the pins l39 prevent endwise oraxial movement of the shalt 35. The sprocket 36 has a sprocket chainconnection 40 with the sprocket wheel 7 of the crank shaft. Rotatablewith the shaft 35 are worms t1 and 42, which mesh with the worm teeth 43of the iianges it ot the lower parts of the cylinder valves 28 and 29.1t is. to be seen that by virtue ot these connections that the cylindervalves 28 and 29 will rotate, in order to correspond with the intake ofa charge, the compression thereof, the hring ot the same, and finallythe exhaust of the utilized gases. Mounted in the wall of each cylindercasing is a stub pin 46, secured in position by the nuts 47, and on theinner end of the stub pin a roller 48 is mounted for engaging the undersurtace of the tlange fit of each cylinder valve tc support the same inposition as it rotates. and 10 additional intake and exhaust ports t9and 50 are provided, in which case the intervals between the explosionsmust neces-y sarily be decreased; hence the gearing between the cylindervalves 23 and 29 must necessarily be changed accordingly, but whichaltered connections are not shown.

it will be seen that the stub-pin e3 previously-referred to has its twoends otlset with respect to each other, giving it the shape ot a crank.By the roller 18 being on this cranked end, the stub-pin 4:7 can beloosened in. the casing and the roller i3 adjusted to compensate tor anylongitudinal wear that may have occurred in the cylindrical valve.

'ln so far as the operation ci this engine concerned, it is onlynecessary to 'forth the operation ci one cylinder, it is to hennderstood that the pistcns oi both cj ders alternate in their cycles otoperations. Referring to the piston 13, it is to be seen that as saidpiston starts on its downward Athe intake port 26.

vcompressing the charge.

stroke, the charge is fired, as a resu nl rigs. 7, e, 9-

intake for a certain stroke, one or the other of the ports 31 and 32 isbeginning toregister with the intake port 26,`thereby sucking in acharge. After the piston 18 reaches the end of its down intake stroke,either one of the ports 31 and 32 has passed out of registration withThe piston 18 then starts on its upward compression stroke,

Immediately following the completion of the compresiori t o which thepiston moves downwardly. The piston, after completing the liring stroke,starts upon its upward stroke, just about, or substantially `alittleafter one or the other of the ports 31 and 32 begins to registerwith the exhaust port 27, thereby exhausting the utilized gases.Therefore, substantially at the time Vthe piston completes its exhauststroke and instantly subsequently starting on its next intake stroke,one or the other ot the'ports 31 and 32 is beginning to register withthe intake port 26. llt is to be noted that the gearing between thecrank shaft 6 and the cylinder valve is of such design and constructionas to operate the cylinder valve so that said ports will registerapproximately at the time as above set orth, it to be understood thatthe pistons of both cylinders carry out the foregoing cycles ofoperation alternately. 'in an engine involving the construction andarrangement of intake and .exhaust ports such as shown in Figs. 7 to10iinclusive, it is to be understood that the gearing between the crankshaft 6 and the cylinder valve should be so designed and vconstructed asto rotate the cylinder valves of both cylinders at 'Easter rates ofspeed than the cylinder valves shown in Fig. 1, owing to there beingjust double of intake and exhaust ports to those shown in Figs. 2, 3 and@l and 5. rllhe gearing for providing this increase of speed can consistof the same parts as disclosed in Figs. 1 and 6, with the exception thatthe teeth and threads of the worm wheels and the worms may beconstructed on a greater pitch.
